struction thereof as will be hereinafter fully described and pointed out in the claims.

More particularly the invention relates to the type of locomotive utilizing the trucks for drivers. Commonly these have been used for logging purposes and are ordinarily driven by a geared longitudinal shaft. It is desirable to distribute the weight on these locomotives so asto have equal weight on all the drivers. It is often also desirable to extend the boiler and in this connection it is desirable to have the front saddle operate on the smoke box" rather than the boiler in order that the joints may not interfere with the boiler.

In the present invention these desirable fea- "tures are carried out.

- Figure 1 shows a plan new of a locomotive frame. Fig. 2 a side elevation-of a locomotive. Fig. 8 a central vertical section 'of'the front end of the locomotive frame,

boiler and smoke box, the section being on the line 3-3111 Fig. 1. Fig. 4: a. sectio end. 5 marks the boiler and 6 the engine,"

on the lines H in Fig. 1.

1 marks the reartruck of the locomotive, 2 the front truck and 8 the side bars of the locomotive frame. This frame is ordinarily formed of two bars 3 trussed in the center, the bars being brought together at the front the engine being arranged with cylinders placed at an angle operating at a centrally located longitudinal shaft as shown in Fig.

; motive.

2. The shaft, however, in this figure is not carried into the trucks but this will be understood from this common type of loco- Steam is carried from the boiler through the pipe 7 to the engine and is ex hausted by way of the pipe 8. The front bolster 9 extends betweenthe side frames 3 and is provided with the swivel 10 which operates in connection with the spring bar 1170f the truck in the ordinary manner.

The front saddle 12 is arranged between the Patented Jan. 4, 1916.

side frames and is off-set from the bolsterv from the bolster to the buffer bar or front bar 18 of the locomotive frame. This is carried under the saddle.

In the ordinary construction the saddle 12 is placed directly over the bolster. This reduces the weight carried by the front trucks so that there is ordinarily an improper distribution of weight. The present construction permits the extension of the boller still retaining the trucks at the"origi-.

nal position so that there is a greater proportionate weight on the front trucks than before the, extension. It also permits, with this extensiom'theconnection of the saddle with the'smoke box so there is no difiiculty ,of weakening the joints of the boiler itself. Furthermore, there is a slight spring in the frame between the point of support of the bolster and the saddle which relieves the ticularly advantageous where the frame is made of the double bars 3 with the double bars brought togethertoward the forward end of the frame. r What I claim as new is 1. In a locomotive, he combination of a front truck; a frame; a boiler; a smoke box in front ofthe boiler; a bolster on the frame 7 resting on the truck; and a saddle carrying the boiler ofl-set in front of the bolster.

2; In a locomotive, the combination of a front truck; a frame; a boiler; a smoke box in frontof the boiler; a bolster on the frame resting on the truck; anda saddle secured to the smoke box for carrying the. I boiler, said saddlebeing off-set in front of the'bolster. I j

8. In a locomotive, the combinationof a front truck; a frame formed of two parts separated through the central portion and brought together along the forward'end of the frame; a boiler; a smoke box in front of the boiler; a bolster on a portion ofthe frame in which the bars are together, said bolster resting on the truck; and a saddle carrying the boiler and secured to the frame in front of the bolster.

4. In a 1ocomotive,the combination of a front truck; a frame; a boiler; a smoke boxv 80 boiler of some of the shock. This is parin front of the boiler; a bolster 0n the frame my hand in the presence of two subscrihzng restlng 0n the truck; asadclle carrylng the \vltnesses.
